The heads are connected by the usual foldin g leather sides F, and areprovided with the necessary reception and discharge valves G H I J.

By the use of the V-shaped head C, which oscillates on the partition D,two forcing-chambers, K L, are constructed, the alternate action ofwhich produces a uniforrndisoharge'of air into the commonreceiving-chamber M.

Two or more discharge-pipes, ,N O, connect with the receiver, theventage of which can be governed at will by means of valves P g.

The bellows are connected to and operated by a revolving shaft, E,through rod S, lever T, rod U, and crank The shaft is provided with anordinary flywheel, and can be operated at will by either pulleyW, leverT, treadle Y, or handle X.
